Default servlet
How force Tomcat4 to call default page
from index.jsp to index.class(Servlet)?
Any settings in web.xml?If so how?

Posted by Richard P <rp...@yahoo.com>.
Pass value either in a hidden form field or appended
to the URL like submitID=SOMERANDOMID.
Upon processing the form, first check to see if
SOMERANDOMID has already been saved to a
cookie/session variable. If yes, error message "This
form has already been submitted". otherwise, save
SOMERANDOMID to the session or in a cookie.
I like to leave a submit_it_again_anyways link for
power users.

how to prevent hitting back button and re-executing code?
Posted by C Cayetano <ap...@ccayetano.com>.
All,
Problem:
I've got a name.jsp page which has a form to get lastname, firstname,
address, etc.
On submit the form is sent to a servlet for adding into the database
(primary key field is an incremental record ID)
Once processed the servlet redirects to a confirmation.jsp page
Now if the the user hits the back button, which pops a 'retry' dialog box,
and the user hits retry button, the whole add process is executed again and
the same lastname, firstname, address, etc. is entered into the database,
basically creating duplicate records.
Is there a way to prevent this?
Thanks

Is it possible without redirecting and doing any settings in server.xml?
Is there any trcicks to be java servlet as default "welcome" file
instead of index.jsp?
